Title: Improvements in or relating to sealed contact assemblies
IPC: H01H51/28
Filed: 1965-08-10
Abstract: 1,103,348. Electromagnetic relays. SIEMENS A.G. 10 Aug., 1965 [11 Aug., 1964], No. 34107/65. Heading H1N. The contact blade springs 1, 2 of a sealed magnetic contact device have longitudinal stiffening patterns 10, 11 formed at the leadthrough regions 3, 4 of the enclosing tube 5 which patterns extend into the tube. Since the origin of spring deflection is the end of the stiffening pattern this arrangement ensures that the variation in the size and location of the seals of different devices does not affect the spring characteristics. The stiffening patterns also extend externally of the tube to prevent damage to the seals by external electrical connections. A marking, e.g. slot 12 identifies which end of spring 2 is which for automatic production. The pattern may be an X-shaped (Fig. 2, not shown), or Y-shaped (Fig. 3, not shown) embossment or the spring may have a channel or arcuate section where it is led through the tube (Fig. 4, not shown). Thus the contact springs of contact assemblies with different characteristics can be made from identical blanks using the same, tools except for the stiffening tool.

Title: Improvements in or relating to light polarizers
IPC: G02B27/28
Filed: 1945-12-20
Abstract: 605,489. Polarizing apparatus. KODAK, Ltd. Dec. 20, 1945, No. 34572. Convention date, April 1, 1943. [Class 97 (i)] A multi-layer material for polarizing light of wavelength # comprises a plurality of thin transparent layers, each of which is of uniform thickness and forms a refracting interface with the adjacent layers, the alternating and intervening layers having different indices of refraction N1, N2 respectively, the alternate layers each having a thickness approximately ##N1<2>-N2<2>/4N1<2> and the intervening layers a thickness of ##N1<2>+N2<2>/4N2<2>. The principle of the invention is illustrated in Fig. 1, which shows alternate interference layers 11, 12 of refractive indices N1, N2 united between components 10, 13 of indices N3, N4. The thicknesses of the layers 11, 12 are such as to increase reflection at a certain angle which is such that the ray 14 will be incident on the interfaces between layers 11, 12 at the Brewster angle, whereby reflected and transmitted rays are polarized and the reflection is enhanced by interference. The layers 12, 11 may be of zinc sulphide and magnesium fluoride respectively and may be sandwiched between glass plates, between the hypotenuse faces of rightangled prisms, or between such a prism and a rhomb, the reflected and transmitted beams passing perpendicularly through their respective exit surfaces. Alternatively, three interference layers on each prism component may be united by adhesive. The theory of the invention is discussed. Specification 551,548 is referred to. The Specification as open to inspection under Sect. 91 describes a polarizer formed by coating a strip of transparent material with an interference layer, dividing the coated sheet into units and cementing the units in layers. This subject-matter does not appear in the Specification as accepted.

Abstract: 1435805 Removal of SO2 from effluents; calcium sulphate COMBUSTION ENG Inc 25 July 1973 [27 July 1972] 35461/73 Heading C1A Flue gas containing sulphur dioxide as contaminant is scrubbed with an aqueous solution containing CaSO 4  and excess NaOH, part of the NaOH reacting with the SO 2  to form bisulphite ions which are oxidized in a subsequent step to sulphate ions, the oxidized solution being then contacted with CaO to form CaSO 4  which is filtered off and the NaOH containing filtrate is recycled to the scrubbing stage. The excess of NaOH is such that during the scrubbing a pH of about 5À0 to 5À6 is maintained. Air is the preferred oxidizing agent and after the oxidation the pH drops to 2À0 and any CO 2  which has been absorbed is driven off with the stream of air. Make-up water and make-up sodium sulphate may also be added at the oxidation step. Limestone may be calcined to form CaO which is added to the oxidized solution in a causticizer regenerating NaOH and forming a precipitate of calcium sulphate. Any fly ash washed out of the original gas stream comes down with the calcium sulphate precipitate. The filtered solids may be washed in a centrifuge and the wash water and filtrate returned to the scrubbing stage. Make-up NaOH may be added to compensate for any loss during the process. If desired the oxidizing and causticizing steps may be combined, or the lime may be slaked prior to its addition to the oxidized solution. Also a series of causticizers may be used.

Abstract: 913,220. Winding yarn packages. OWENSCORNING FIBERGLAS CORPORATION. Oct. 20, 1959 [Nov. 3, 1958], No. 35584/59. Classes 120 (2) and 120 (3). A package of filaments of mineral or resinous material is formed by first winding on a minor area of a sleeve a narrow band of filaments of a width equal to the amplitude of oscillation of the filaments and in which the filaments cross each, followed by laying down the main layers of filaments with convolutions of filaments in crossing relation throughout the layers. The narrow band is intended to provide a visual signal indicating the approach of the end of the filaments when unwinding. The signal band 24, Fig. 2, may be disposed on any part of the sleeve 10 and is formed by allowing the filaments to be guided on to the sleeve by a traverse means 110, Fig. 5, which, during the formation of this initial layer, is not reciprocated. A motor 114 rotates the traverse means 110 and is arranged to cause its reciprocation through mechanism driven by a belt when an idler pulley tensions the belt under the influence of a solenoid 188. Upon completion of the winding of a package, a treadle 96 is depressed to apply brake shoes to a drum mounted on the packagecarrying shaft and to stop the motor 70 that drives the package. Release of the treadle 96 permits winding to begin again, but time delay apparatus, by holding the idler pulley away from its belt, defers the start of reciprocation of the traverse means 110.
